Best Solar Pool Heaters

Durable but lightweight, this solar cover fits above-ground pools well and does an impressive job heating the surface on sunny days. Damage to its bubbles will reduce its performance, though.

Can raise a pool’s surface temperature by 10 to 15 degrees on sunny days, and as much as 20 degrees in some climates. Very durable despite its thin construction.

12' Solar Blanket for Round Pools

Doesn’t hold heat at all. Will have trouble fitting certain pool rims, even at the correct size. Bubbles may flatten out with storage, reducing its heating capability.

Best Bang for the Buck

Splash Pools

Easy to take on and off the pool surface, though its thin construction means its service life is only about one season.

Light enough for one person to float onto the pool surface without breaking surface tension. Heats the pool surface quickly on sunny and on hazy days. Stays in place even on windy days.

Cover can disintegrate after just a few months, scattering blue dots all over the bottom of the pool.

Blue Wave

Its thin construction is a trade-off: easy to float on and off the pool surface, but it deteriorates quickly after a couple of swim seasons.

Brings above-ground pools’ temperature up by 8 to 10 degrees on sunny days. An added plus: it catches debris that would otherwise sink in the pool, making fallen leaves and twigs easier to clear away. Lightweight and easy to put on. Can be trimmed to size.
